Lesson 16
Compare Fractions with the Same Numerator
Lesson Purpose
The purpose of this lesson is for students to compare two fractions with the same numerator.
Lesson Narrative
In this lesson, students reason that fractions with the same numerator have the same number of parts, and that the denominator shows the size or length of those parts. Students recognize that as the denominator increases, each part gets smaller. It is important that students develop this understanding rather than learning a rule about comparing fractions with the same numerator.

Teacher Reflection Questions
As students worked in their small groups today, whose ideas were heard, valued, and accepted? How can you adjust the group structure tomorrow to ensure each student’s ideas are a part of the collective learning?
